Re: QuartzPlugIn for struts manual scheduling

[klute]

Ram,

Thanks a lot. Dunno how I missed that..

For all of you out there who needs an example of this
functionality:

QuartzPlugIn qp = (QuartzPlugIn)
request.getSession().getServletContext().getAttribute(QuartzPlugIn.PLUGIN_KEY);

Scheduler scheduler = qp.getScheduler();


Best,
James
